Pink is for girls, so it must be bad?

I've never been bothered by the pink-is-for-girls, blue-is-for-boys thing. It's utterly arbitrary. The way it's used to enforce gender roles is irksome, but a world where the colors had the same gendered associations but people weren't expected to necessarily lead such gendered lives - that would be fine by me. If that association were somehow tied to biology? Fine, whatever. So when I see a Feministing post disparaging a study that purports* to show an innate preference for pink in women, my first thought is, "Who cares?"
